Formetis is a set of automatically generated bindings to the METIS and ParMETIS graph partitioning libraries. With the default settings of 32-bit reals and floats, the installed Formetis library requires nothing but a Fortran compiler, and building requires a C compiler. If building with a modified (64-bit) version of METIS, the SWIG-Fortran tool is required to regenerate the bindings.
This library is primarily a proof of concept, a demonstration of rapidly adding Fortran bindings to an external library. For a better-documented library in high-level Fortran, see the unaffiliated Fmetis project.
